Answer : The pressure it exert under these new conditions will be, 87 atm
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 19 atm
= final pressure of gas = ?
= initial volume of gas = 100 L
= final volume of gas = 20 L
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Therefore, the pressure it exert under these new conditions will be, 87 atm
In Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From Lewis structure it is shown that the Nitrogen atom also contains a lone pair of electron.
So,
According to Valence Shell Electron Pair Repulsion (VSEPR) Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only three are bonding pair electrons and one lone pair electron. Now, due to presence of lone pair of electron (which has greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from 109° to 107° and results in the formation of <span>Trigonal Pyramidal geometry as shown below,</span>
